A couple things to point out, MINOR SPOILERS.
The Lover's Retreat scene with Rhianna just shows a black screen. I don't know if you've not made it yet, or if its a matter of who's in what form, but it doesn't seem to work. Also with Rhianna, when I tried changing her house at the same time she was a hyper, she had four tits, and the weird part was that I couldn't tell by the graphic whether or not she was meant to have four, none of it looked right in either regard. I don't even know what might be happening there.
Update: That seems to only happen if she's naked, I was trying out the nudist toggle at the time. It looks like its loading her breasts from both her clothed and nude states.
As a side note, wouldn't mind being able to undo certain changes. Case in point: Change Akarion back after the initial change in order to gain his trust. I feel like certain options being repeatable or reversable would help.
